School Compensation Systems: Salaries vs. Grades

Schools reward their inhabitants in two amazingly different ways: teachers get salaries, and students get grades. Not only are these systems vastly different, but I'm not sure teachers would accept a pay scale that's built like a grading scale, nor would students accept a grading scale that's built like a teacher's pay scale. The vast majority of schools pay teachers according to a "salary schedule," a rigid, two-dimensional matrix of dollar amounts with credits across the top and experience down the left side. The more credit hours you've earned, and the more years you've taught, then the more you'll make. I don't feel it's a fair system, but it's a system that most teachers will agree to use, putting it ahead of most any other pay system available. It's a simple system, perhaps too simple. Its simplicity allows us to easily print and read the salaries on a sheet of paper, and I think that's one reason we continue to rely ...

The Myth of the Slipping Math Student?

Image
I've been teaching in Colorado for six years, and there's always been a troubling pattern in our state standardized math scores. As students progress from 3rd to 10th grade, the percentage that score proficient and advanced declines dramatically. Here are the percentages of students scoring proficient and advanced by grade level, averaged over all the years the test has been given (typically 2002-2008): Grade Avg. % P+A 3 69 4 69 5 61 6 55 7 44 8 43 9 34 10 29 The easiest explanation (and the one I've tended to believe) is that students' abilities are, in fact, slipping as they got older. That would be a good assumption if the test at each grade level was equally difficult. But what if the test questions were, on average (and adjusted for grade level), more difficult as students got older? Is it fair to assume a test with increasingly difficult questions would result in lower scores, even with sophisticated score scaling systems that take question difficulty into accou...
